.Application led March 2*?, 1926.

This invention relates to that class of kilns in which the lire is carried around the kiln in fines so as to heat the interior Walls of the kiln to incandescence and through thein `the contents of the kiln without the flue gases coming in contact with the contents.

'llhe invention has for its object a greater economy of fuel and a. incre uniform distriloution of the heat.

The invention comprises a kiln in Which are combined an interior Wall and an exterior Wall with fire holes at the sides and flue leading from the fire holes under the floor of the kiln, then up the further side and over the top in a diagonal direction, then down the other side and again across under the floor but this time in a line interniediate the lire holes, the flue .finally dehouching into a coinrnon longitudinal tunnel leading to the stack.

TDetailed combinations involved in the invention Will leest he understood in connection with the accompanying drawing in which:

Figure l is a transverse vertical section through the kiln, taken on line l-l of Figure 5.

Figure 2 is a front view of one of the fire holes on plane 2 2 of Figure l.

Figure 3 is a partial horizontal section on line Z-lw'of Figure l.

Figure l is a vertical `transverse section of an alternative construction of under the floor dues, on line and of Figure l.

Figure 5 is a horizontal section on line 5%5 of Figure l.

Figure (i is a horizontal section half Way up the furnace on line 6-6 of Figure l.

1T igure .7 is a horizontal section on line 7-7 of Figure l, showing the flues over the top of the kiln rlhe kiln consists essentially of an inside Wall l, a floor 2, an outside Wall 3, and a sub-floor t. Both the inside and outside Walls are arched over the top. At 5 are shown the usual fire holes in Which any forni of lire niay he created, preferably an oil Serial No. 97,943.

burning flame. Freni these fire holes floor supporting partitions forni under floor flues G which extend straight across the kiln. They may he inade double With a longitudinal partition in the center for the better support of the floor or single with arc-hed ceilings as shown in Figure 4. At the side oit the kiln opposite t-he fire hole, these par tit-ions are continued upward and over the top of the arched ceiling and then doWn- Ward, thus forming uptakes 7 and downtakes 8. Upon reaching the level of the under floor linesJ the partitions including again a central support, pass across under the floor again, and finally at the further side of the kiln from the fire hole open into a stack tunnel 9 which leads to a stack lO. An inspection of Figure 5 Will show the relative arrangement of the under floor flues, those leading direct froin the fire hole being in` dicated hy 6 and those leading to the stack tunnel being indicated by ll, the port into the stack tunnel from the under floor flue being shown at l2. This ligure also shows that the entire under floor space with the exception of the space occupied by the partitions supporting the floor, is occupied by ues that will insure a uniform heat all over the floor. In this figure also is shown by dotted lines the oblique partition between the lues over the top of the kiln at 13, see also Figure 7.

l claim ln a kiln, the combination comprising double floors and double Walls, arched over the top, said Walls having a plurality of fire holes in the side With partition Walls forining llues extending from the fire holes across the kiln under the kiln floor, then vertically up the further side between the walls, then diagonally over the top of the kiln and vertically down the other side, then again across under the kiln floor in lines intermediate the fire holes and a longitudt nal stack tunnel With which the ilues finally connect.
